To all whom it may concern:

Be it known that I, EMMET L. VAN DoL- SEN, a citizen of the United States, residing at Berwyn, in the county of Cook and State of Illinois, have invented a new anduseful' Wheel for Traction-Engines, of which the. following is a specification.

This invention relates to wheels for traction engines and its object is to provide a wheel of this character having adjustable spuds which can be shifted so as to adapt the wheel for use upon roads of different kinds and conditions, it being possible to entirely retract the spuds into the lowermost portion of the wheel so as to present a smooth surface to the road.-

Another object is to provide a wheel of this character designed to automatically clearitself of all dirt or otheraccumulations upon the rim thereof, the spuds acting there on in such a manner as to thoroughly loosen it from the rim.

.Another, object is to provide means for scrapin the tread of the wheel.

Another object is to provide a wheel constructed in a novel manner the various parts of which can be conveniently replaced inthe event of wear or breakage.

With these and other objects in view the invention consists of certain novel features which will be hereinafter more fully describ ed In the accompanying drawings is shownv In said drawings: Figure 1 is a viewpartly in side elevation and partly in section of a wheel embodying the present improvements. l i 2 is an elevation of a portion of the tread, the upper portion of the wheel being shown in transverse section. Fig. 3 is a detail view of one of the spuds detached.

Referring to the figures by characters of reference, 1 designates an axle preferably jour'naled within a sleeve 2 secured to the gine and this axle has a worm gear 4 keyed or otherwise secured to it and driven by a worm '5 mounted on a shaft 6 to which a gear 7 1s also secured. This gear is disposecLto be actuated by a gear 8 secured to a shaft 9 having a hand wheel 10 or other suitable means wherebthe same can be conveniently actuated y the operator. Axle 1 extends bei curedto this projecting portion of the axle is an eccentrlc 11. Hub sections 12 are arranged upon the axle at opposite sides of the eccentric and a series of anti-friction rollers 13 is preferably located between the axle and the hub. The hults are held against move- .ment longitudinal to the axle by means of a .collar 14 formed upon the sleeve 2 and by a cap 15 which is fastened to the axle in any suitable manner, as by means of a cotter pin.

cated within each hub forcontact with the rollers. Each hub 12 has spokes 17 radiating therefrom and connected to or formed .with a ring 18 having an outwardly extending annular flange 19. Secured upon the two flanges 19 is a metal band 20 constituting the tread of the wheel and this band is provided at regular intervals with transverse slots 21 extending preferably from one ring 18 to the other. This band, together with the ring, spokes, and hubs constitutes the body of the wheel. A drive sprocket 22 is mounted to rotate upon the sleeve 2 and is connected to certain of the s' okes of the inner ring 18 by means of stu s 23 or in any other desired manner.

' Mounted upon the eccentric 11 and between the hubs 12 is a wheel 24 having a flat rim 25 provided at regular intervals with apertures for the reception of pivot pins 26.

Thesepins equal in number the slots 21 and each extends through sleeves 27 formed at the ends of arms 28 extending from a blade 29 forming a spud. The arms and blade are.

preferably reinforced by means of webs 3-0 as shown particularly in Fig. 8. The arms 28 straddle rim 25 and are designed to oscillate upon-their pivot pins 26, said pins-being held againstdisplacement within sleeves 27 in any preferred manner as by means of cotter pins 31.. Each spud is designed to extend loosely throu 11; one of the slots 21. The arms 28 of one o the-",Spuds have extensions 32, which lextend along opposite faces of one of the spokes 33"'of.w1heel 2 1 and these extensions are bolted to the spoke as indicated at 34 so as to hold the arms 28 of said spud in fixed relation to the wheel 24. The other spuds, however, are pivotally connected to the wheel as heretofore stated.

A wear sleeve or bushing 16 is preferably 10- A rock bar 35 is journaled upon the structure 3 and has hangers 36 secured to it at points above the traction-wheel, and these hangers are connected by a scraping blade 37 designed to extendthe entire width of the traction wheel and to rest upon the treadthereofa Any suitable means,"not shown,

may be employed for actuating the rock bar so as to move the scraper into or out of con- 1 tact With the wheel. j

When it is desired .to project the spuds as far as ossible into the ground, as for example,'-'w enlthe ground is very soft and when considerable tractive ower is desired axlel is turned by means of the shaft 9 and the gears operated thereby until the eccentric 11 is turned downward as far as possible. This will throwthe wheel 24 downward and. cause the lowermost spuds to be rojectedbeyond the tread of the Wheel, whi'e-theup ermost spuds will be retracted into the whee as indi- 'cated in Fig. 1..

ce'ssively projected beyond the tread 20 as ,they move downward during the rotation of,

the wheel and afterthey pass the lowerm'est portionof the wheel 'they'will be gradually retracted during their: upward movement.

- This results in a slight oscillatory action of each. spud which serves during the 11 Ward movement ofthe spud to'thoroughly oosen "by preventing dirt, etc., from being drawn from said point of contact. When the Wheel.

any dirt or other accumulations upon the spudand adjacent portion of the tread there into the wheel by the spud. By placing the scraper in contact with the tread at the point where the spuds are retracted all dirt, etc., can be thereby. f,

. Should the ground behard it would of course be undesirable to project the spuds thereinto "fora considerable distance and therefore by partly rotating theeccentric 11 the'point of the greatest rojectionof the s uds can be shifted from dhe point of contact e'tween the wheel and the'ground to a desired distance 7 As the eccentric 11 remains stationary it will be apparent that asv the traction wheel revolves the spuds will be sucquicklyv removedfrom the tread,

anaestwhich the spud is located so as to preventthe same from beingdrawn into the Wheel with the s ud. As a result the mechanism" of the It. will be seen that the wheel is very simple,

durable and efficient and by constructing the parts in the manner described any one or more of them can be readily replaced in the event of Wear or breakage.- 'lhe relatively fixed spud having the extensions 32 is pro- .Whee is kept practically cleaned at all times. U

vided to prevent-independent rotation of the l wheel 24 and the tread 20.

What is claimed is;

1. Atraction wheel comprising an axle havingan intermediate-eccentric portion, means for rotating the axle, hubs upon the axle at.

opposite sidesof the eccentric portion, said axle being mounted to rotate within the hubs, spokes radiating from each hub, rings carried by the spokes of the hubs," a band se- I cured to the rings and constituting the tread of the ,wheel, said band having transverse slots the ends of which'ar e flush with the in:

ner or adjoining faces of the rings, an inner wheel mounted upon the eccentricportion and 'shiftable thereby, a series of spuds car-- riedby said wheel, each spud consisting ofa blade" movably mounted in one of the slots, arms extending from the blade and straddling the peripheral portion ofthe inner Wheel,-

through the sleeves and the inner wheel and held against longitudinal movement therein and webs interposed between the arms and,

extending from. said arms to the end portions of the blade, and means for preventing independent rotation of the inner and outer Wheels.

- '2. A spud for traction wheels comprising a fblade having integral parallel arms. extending perpendicularly from one edge thereof, each arm having a bearing sleeve at its free end, the two sleeves being disposed in aline ment, there "being reinforcing webs extendsleeves upon said'arms, pivot pins extending ing from the arms to the ends of the blade and between the arms. j j y In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence'oi two Witnesses.
